I am trying to install xmpp on Linux, i found the following links
I have an IOS application and i need to build an IM using jabber/xmpp in it. There by allowing users on the application to chat among themselves.
To do this i am trying to install XMPP on the server. So, I want to know how the communication is established between
Application User-- Server -- Application User
How a User utilizes the xmpp configuration to send messages to another user ?
Can't IOS itself have the configuration? Is it necessary to install XMPP on server to accomplish this task?
The examples i came across so far based on Window--window application(Web based).
Can anybody explain the actual process of communication take place? How an IOS user connects to XMPP installed on my server?
